Howto remove a printer in the printing manager?

Because it's a remote printer, and you cannot remove remote printers,
this needs to be done on the computer where those printers are defined.
But you can "hide" those printers using 2 ways:
1) filtering the printers shown, filtering is configured in the
   KDEPrint settings dialog (Print Manager -> configure manager
   -> Filter)
2) disable browsing for your local CUPS server, so it won't see anymore
   printers broadcasted by other computers on your LAN.

KDE print manager does not "add" the remote printers, the fact is that
those printers appears only a certain time after CUPS restart. Just try
to restart the CUPS server, wait a few minutes (to be sure), then
visit http://localhost:631/printers

Because they are remote printers == print queues installed on other
computers.

Because you can only remove local print queues.

I doubt you're actually removing the printer, even from the web admin
tool. What you do is to remove the local image of the remote printer,
until browsing is updated again, which make the remote printer
to re-appear. Just try to remove the printer from web interface, then
wait a few minutes and refresh the page http://localhost:631/printers
